Default Re: cummins 5.9 fuel line leaks

Tighten the new one carefully so the support/vibration bracket has no stress on the line. #6 occasionally cracked until a support bracket was added around 2005 or so; it goes to the engine lift bracket bolt that is converted to a bolt/stud. #4 is the most common one to fail for some reason. Get it from Cummins for about $25-30.
